How can I detect PDF policy of ImageMagick

Question

I maintain qr-backup, a program which makes some PDFs.

My users are encountering a bug where convert fails on PDFs. Why and how to fix it is explained here. imagemagick - convert not allowed

What's a simple, fast test I can do (for example with convert) to tell whether they're being hit by this policy issue? I'd like to print them a clearer error if they're on an affected OS.

Yes. Your program should read that line in the file and check for the value "rights=none". Are you asking for the code? Your question doesn't specify. — Organic Marble, Sep 21 '22 at 11:35

Check the exit status code below (0 for no policy problem)

convert -size 1x1 canvas:white pdf:- >/dev/null

Or of this (0 indicates policy problem)

grep -s -q 'policy domain="coder" rights="none" pattern="PDF"' /etc/ImageMagick-6/policy.xml
